About the 750-AAYM
The Dell 750-AAYM is a Dell PowerEdge R740 Standard Fan Module (Silver Grade) engineered to deliver high-velocity cooling airflow across internal server components. Featuring a dual-rotor counter-rotating motor design, the 750-AAYM provides static pressure to cool high-wattage processors, memory banks, and expansion cards in high-density Dell PowerEdge chassis. The 750-AAYM maintains safe operating temperatures under continuous datacenter computing loads.
Compatibility
Designed specifically for Dell PowerEdge R740, R740XD servers, the 750-AAYM installs into the central hot-plug fan bay. The 750-AAYM integrates with chassis fan brackets and connects through blind-mate power pins for tool-less replacement during server operation.
How to identify a genuine unit
Genuine Dell 750-AAYM fans display a factory label showing DP/N 023Y5M, Delta or NMB manufacturer markings, and operating voltage/amperage specifications. In iDRAC Fans inventory, the 750-AAYM fan reports real-time RPM speed and operational health status, allowing predictive maintenance alerts.
Buying used
When evaluating a pre-owned 750-AAYM, spin both fan rotors manually to ensure bearings rotate smoothly without grinding, resistance, or wobbling. Check the plastic housing and blind-mate connector pins on the 750-AAYM for physical damage. Confirm in iDRAC that the 750-AAYM modulates PWM speed normally under thermal stress.
